1966 Map of Carter Reservoir

About this map

Long Valley (Depression) dominates this high-desert borderland where the boundaries of California and Nevada meet those of Modoc and Washoe counties. The landscape is defined by its vital water sources, ranging from the prominent Crooks Lake in the north to the Carter Reservoir and Mud Lake further south. These basins and ephemeral sinks are supported by a network of named water points including Big Spring, Willow Springs, and Juniper Spring, which were essential for ranching and travel in this arid region during the mid-1960s.
